It was all more or less of a puzzle to her, but it was one which her taskmaster never explained further than the revelations of each day explained it. She understood that he was a scientist, that he undoubtedly had been an operator in some surgical field or was putting into shape the work of another in that field, but what he now was besides a writer of technical books she had no manner of idea. "But I really enjoy it, Father Davy," she insisted, when she came down to him one day with hotly flushed cheeks and shaking hand after a particularly protracted siege of copying involved and incomprehensible material. "It's monotonous in a way, but it's intensely interesting, too. Mr. Jefferson is so absorbed in it, it's fun to watch him. To-day he was as happy as a boy over a letter he had just received from a Professor Somebody, a great authority in Vienna. It seemed it absolutely confirmed some statement he had made in a monograph he wrote last year which had been challenged by several scientists. The way he fell to writing his next paragraph after he had read that letter made one imagine he was writing it in his own heart's blood. He read it aloud to me." She laughed appreciatively at the recollection. "Could you make anything of it?" inquired Mr. Warne with interest. "Not very much. It was about the pituitary body;--oh, I've come to have a great awe of the pituitary body, it seems to be responsible for so many things. He chuckled over it like a boy, and said to me, 'Forgive these transports, Miss Warne, but this is food and drink to me. I wish I could explain it to you so that you might rejoice over it with me. Some day I will, when we are not so busy.' I hope he will. There's enough that I do understand to make me interested." "I see you are--and rejoice, my Georgiana. Do you remember what Max Mueller says, echoed by many another, '_Work is life to me; and when I am no longer able to work, life will be a heavy burden?_'" He smiled as he said it, but his daughter read the seldom-expressed longing in the cheerful voice and laid her cheek for an instant against his. "He's quite right. And you have your work, Father Davy, and you're doing it all the time. I think you preach much more effectively now than you did in the pulpit, even when you don't open your mouth. And when you do open it angels couldn't compete with you!" They laughed softly together, though Mr. Warne shook his head. "It's a curious thing," he mused, "that the weaker the body gets the harder does the mind have to strive to master it. But, thank God--'_so fight I, not as one that beateth the air_.'" "'Not as one that beateth the air,'" murmured the girl. "I should say not, Father Davy. As one that delivereth hard blows on his own body, his poor, tired body. Oh, if I had one tenth the self-control----"
